Check if you have ec bios chip, flash that too. Check first if there's voltage running on that chip.

No schematics for Wistron Z70CR, but attached is a schematic for Z40HR. May be similar enough. Please try to make the correspondance between your board and this schematic, as it will be easier to troubleshoot.
Especially explain what U6001 and U6002 are.
